Find the zeros of the function in the interval (-2 pie, 2 pie). f(x) = 3 cos x

Roots are -π/2 and π/2

Step-by-step explanation:

when x is -2π:

hence -2π is not a zero of the function

when x is 2π:

hence 2π is not a zero of the function

when x is π/2:

Hence ±π/2 is the zero of the function.

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)

have a good day!

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
